SPEGIFIOATION forming part of Letters Patent No. 621,218, dated March14, 1899.

Application filed September 21, 1898. Serial No; 691,497. (No model.)

Yb al'ZZ whom it may concern:

Be it known that I, OLIVER O. BURR, a citizen of the United States,residing at North Adams, in the county of Berkshire and State ofMassachusetts, have invented new and useful Improvements in Bobbin andThread Holders for Spindles of Spinning-Machines, of which the followingis a specification.

This invention relates to improvements in bobbin and thread holders forspindles of spinning-machines, the object thereof being to provide asimple, cheap, and effective means for holding the bobbin in engagementwith the spindle and means for holdingand releasing the thread or yarn,the construction of the device being such as to embody in a singlearticle of manufactureabobbin-holder and a thread holding and releasingdevice which comprises in the make-up of the structure a bobbin-holderhaving a plurality of spring-arms carried by the spindle and positionedthereon so as to contact with the periphery of the head of the bobbin tohold and centerthe same on the spindle, the device also including athread-holder'of the type shown in Letters Patent No. 578,810 issued tome on the 16th day of May, 1897.

In the practical embodiment of my invention I employ a thread-holderwhich is of less diameter than the head of the bobbin and abobbin-holder which does not extend materially beyond the bobbin-head,the same comprising resilient arms which engage with the periphery ofthe bobbin-head without projecting above the same.

In the prior state of the art it has been common to provide the spindleof a spinning machine with a bobbin-holder consisting ofoppositely-disposed spring-arms which are carried by the spindle andadapted to be forced apart by a downward pressure of the bobbin, so thatthe bobbin-head would be engaged by the upwardly-projecting ends of thespring-arms, which held the bobbin on the spindle by frictional contactwith the bobbinhead, or with a recess formed in the under side of thehead, means also being provided whereby the thread could be held whiledoffing the bobbin.

The present invention consists in the special construction andcombination of the parts as an improvement upon my patent hereinbeforementioned as well as an improvement upon the type of bobbin and threadholder shown in Patent No. 83,354, dated October 20, 1868, as will behereinafter set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view, partly insection, the section being taken through the bobbin and through thebobbin-holder and thread-catcher. Fig. 2 is a side elevation, thebobbin-holder and thread-catcher being shown in section. Fig. 3 is aperspective view showing the parts separated.

A refers to the spindle to which the bobbin-holder and thread-holder isattached, the bobbin B being of the ordinary type.

a refers to a collar or sleeve, of malleable metal, as brass, copper, orsoft iron, the internal diameter of which is approximately the same orslightly less than the diameter of the spindle where it is desired thatthe parts shall be attached to each other. 7

Z) refers to a disk having at its peripherya downwardly-extending V-shaped flange b,

and between this flange and the central opening in the disk areapertures b Immediately above the disk I) is positioned the bobbinholder0, which consists of a central portion 0 of approximately the samediameter as the disk 19, the same having outwardly or radiallyprojecting arms c'with upturned ends which are adapted to grasp the headof the bobbin. This bobbin-holder has on a line with the apertures 19apertures 0 The parts Z) and C are held in rigid engagement with eachother and are fixedly attached to the collar'or sleeve (1, and, ifdesirable, these parts may be integral with each other.

D refers to the movable member of the thread-holder, which isreciprocally mounted on the sleeve or collar a, the same having anaperture d of slightly-larger diameter than collar or sleeve,upwardly-projecting pins d, which are rigidly afflxed to the upperportion of the movable member D, and a beveled upper edge or periphery dwhich is adapted to engage with the beveled or inner portion of thedepending V-shaped flange b of the disk.

The movable member D, with the exception of the pins, may be spun orstruck up from a piece of sheet metal and the side flares outward, thismember being bell-shaped and of suflicient depth to extendbelow thecollar or sleeve (1, so as to form a cover or protector for the helicalspring E, which is placed over the collar, so as to engage with themovable member I) and a washer F, which is placed over the lower end ofthe collar or sleeve. lVhen the parts are assembled upon the collar orsleeve a,the ends of said collar or sleeve are expanded and upset, so asto hold the parts C b and the washer F in rigid engagement with thesleeve a, the spring and bellshaped member D being movable upon thecollar or sleeve. The pins (1, carried by the member D, project throughthe apertures in the parts I) and O and are engaged by the bobbin-headwhen it is held by the bobbinliolding arms of the part 0.

By the construction shown the parts are all connected and the movablemember of the thread-holder covers the spring, so that there is noliability of the yarn being caught between the coils thereof. Thereciprocal member D is adapted to enter the fixed member, so that thethread when placed between said members will be securely held, and theparts are so shaped as to provide for the automatic taking up of wear.It will be further noted that the parts are so constructed that they areall held together by the collar or sleeve, and said collar or sleeve isadapted to be placed over the spindle and driven to the desired positionthereon, which driving on and expansion of the sleeve will only tend tomake more secure the parts which are in fixed engagement with the same.This improvement is susceptible of application to spindles alreadymanufactured, and when applied it not only serves as a bobbin-holder anda thread-catcher, but also centers the bobbin on the spindle.

The bobbin-holder has preferably three 1'a dially-projecting arms withupturned ends to engage the side of the bobbin-head, though a greaternumber may be used, if desired, and as said arms are attached to acommon center it is obvious that they will center the bobbin on thespindle, which is not the case shouldthe holders which engage thebobbinhead be susceptible of independent movement. It will also be notedthat the threadholder is positioned below the bobbin and its head.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a bobbin and thread holder for spindles, the combination of abobbin-holder connected to a spindle so as to externally engage thebobbin, a part of the bobbin-holder coaeting with a thread holding andreleasing device, the parts consisting of a fixed member and a movablemember, a collar to which they are attached which collar embraces thespindle, and a spring mounted on the collar so as to move one of themembers toward the other and means carried by the movable member forseparating it from the fixed member when the bobbin is placed on thespindle so as to engage the bobbin-holder.

2. A bobbin-holder and thread-catcher for use with spindles and bobbins,comprising a member having a plurality of outwardly-projecting resilientarms which are adapted to engage with the head of the bobbin, a sleevewhich connects the parts and frietionally engages the spindle, a diskfast upon the sleeve and to the bobbin-holder, a movable memberspring-actuated in one direction and movable away from the bobbin-holderwhen the bobbin is placed on the spindle and caused to engage with theretaining-arms of the bobbin-holder, substantially as shown.

3. In a thread-holder for spindles, the combination with a revolublespindle, a sleeve through which the spindle is passed so as to be heldthereon, a disk immovably connected to the sleeve, a member reciprocallymounted on the sleeve, a spring for actuating the movable member towardthe fixed member, a bobbin-holder fixedly mounted on the sleeve andmeans carried by the movable member which project upwardly there from soas to be engaged by the bobbin when it is engaged by the bobbin-holder,substantially as shown.

4. In a thread-holder for spindles, the com bination with the connectingmeans as a collar or sleeve, a disk having a depending peripheral flangefixedly attached to the collar or sleeve, a bell-shaped member, a springwhich encircles the collar or sleeve and engages with the bell-shapedmember to move the same toward the fixed member, the bellshaped memberhaving its upper edge beveled, substantially as shown.

5. As an improved article of manufacture a combined bobbin and threadholder, comprising a bobbin-holder having a plurality ofradially-projecting arms which are adapted to engage with and center thebobbin on the spindle, a movable member constituting a part of thethread-holder the same being spring-actuated in one direction to claspthe thread, pins extending therefrom through the bobbin-holder so thatthe movable member of the thread-holder will be moved away from thebobbin-holder when the bobbin is placed on the spindle so that the headthereof will be engaged by the spring-arms of the bobbinholder, and acollar or sleeve which frictionally engages with the spindle and carriesthe hereinbefore-mentioned parts, substantially as shown.

6. The combination with a collar or sleeve, a disk having aperturestherethrough and a beveled periphery attached to one end of the collaror sleeve, a washer carried by the opposite end of the collar or sleeve,a bellshaped member movably mounted on the collar or sleeve, a springinelosed by the bellshaped member, the spring engaging with the ICCwasher and said bell-shaped member, and pins which extend from thebell-shaped member and pass through the apertures in the disk,substantially as shown and for the purpose set forth.

7. In a thread-holder for spindles, the combination with a sleeve whichfrictionally engages the spindle, a bobbin-holder having three or moreresilient arms for engagement with the head of a bobbin when mounted onthe spindle, a movable bell-shaped member located below thebobbin-holder, for the purpose set forth, and provided withupwardlyprojecting pins which pass through apertures in thebobbin-holder, and a spring for moving the bell-shaped member toward thebob= bin-holder the spring and bell-shaped member being mounted on thesleeve, substantially as shown. i
